Radial Piston Pump PR4-3X/20,00-500RG01M01 - Bosch Rexroth R901089834

The RG01M01 version of the PR4 range differs in its connection diagram and weighs 16 kg. The working principle is unchanged: ten radial pistons, a constant displacement of 20 cm³ and a maximum operating pressure of 500 bar at 26.5 l/min.

Benefits

• 500 bar maximum operating pressure in an open circuit.
• Constant displacement of 20 cm³ and 26.5 l/min flow.
• Ten pistons keep delivery smooth despite the high pressure.
• 16 kg weight, without through-drive, clockwise rotation.
• Serration 21 x 24 to DIN 5481 at the shaft end, 4-hole fastening with 63 mm centering.
• NBR seals for HLP hydraulic fluid in a cast iron housing.

Applications

The pump goes into high-pressure units for clamping technology, tool making and test equipment. Open circuit operation and constant displacement make it a straightforward pressure source that the valve technology in the circuit regulates. The cast iron housing carries the pressure loads and damps running noise at the same time.
